At 1906 G.M.T. May 30, 1962, in lat. 7° 22' N., long. 103° 18'
E., course 166° speed 16.5 knots, dim rays of light were observed. These rays
appeared to be traveling across or under the water and came from a 210°
direction and extended in a 120°-300° direction. They passed the ship at a
rate of 3 per second. At 1910 G.M.T. these rays changed from parallel lines
to curved lines which rotated around a center, which apparently was on the
horizon, in a clockwise direction. The center was bearing 210°. At 1913
G.M.T. the rays became confused and at 1916 G.M.T. another group of rays,
this time on the port bow, appeared. These rays were curved but rotated in a
counter-clockwise direction about a center which appeared to be bearing 120°.
At 1921 G.M.T. the lines became less well defined and slower in movement and
passed the ship at a rate of 2 per second. At 1926 G.M.T. the rays
disappeared altogether. The depth finder was turned on but showed the charted
depth with no variations.
